1 14 Claims.

emptying means are mounted, may be formed of any desired material or combination of materials.

The filling, closing and emptying means herea in disclosed may be mounted on any wall of the container, but is shown mounted on one head thereof (see Figs. 12a and 2B), usually termed the top wall. In the construction of sheet metal containers it has been customary to provide them with two or more openings, each having a bung ring and plug therefor and a sealing means for each plug, one opening for filling andemptying the container and the other or another (smaller in size) for venting purposes. This has required at least two sets of dies for forming the openlugs and mounting the bung rings therein, two tools for applying the caps, the handling of different sized rings, plugs and caps, and extra expense in equipping each container with at least one extra ring and a plug therefor and a cap or sealing means for the plug. My construction eliminates the extra equipment, labor and expense above referred to, since it provides for filling the container, closing it in a liquid tight manner, sealing it against unauthorized opening or emptying, emptying the container and full drainage thereof through a single opening in one wall of the container. However, such novel construction does not preclude the equipment on the container of a separate filling and emptying means as herein disclosed or a separate opening and closure therefor, where such equipment may be desirable.

. One object of the invention is to provide an improved process of mounting on the wall of a container one element of a filling, closing and emptying means.

Another object of the invention is to construct an improved container having a combined closure and emptying means which provide a liquid tight closing of the container and venting thereof during emptying.

Another object of the invention is to construct an improved container wherein provision is made to permit filling and emptying of the container through a single opening in the container wall,

liquid tight closing of the container for shipment,

venting during emptying and full drainage.

Another object of the invention is to construct a container having improved closure means which provide for liquid tight closing, sealing against tampering and venting during emptying.

Another object of the invention is to provide.

in acontainer, improved means for sealing the container against tampering and venting during I emptying.

Another object of the inv'ention is to provide in a container an improved closure and emptying means wherein the element which provides for venting during emptying, also serves as an element of the means to prevent tampering.

A further object of the invention is to provide, in a container, an improved filling and closure means, whereby the filling opening may be liquid tight closed without use of a gasket.

Other objects, of the invention will be apparent to those skilled in the art to which my invention relates from the following description taken in connection with the accompanying drawings, wherein- Fig. 1 is a plan view of that sheet metal wall for a container (end wall or side wall) on which my filling and emptying means are to be mounted, this view illustrating one step of the process of mounting one element thereof.

In the drawings (referring particularly to Figs. 1 to 13, inclusive), i indicates a sheet metal wall of a container, for example, a steel barrel or drum having a body and end walls, such wall being for illustrative purposes shown as the top wall thereof, on which is mounted a filling and emptying means, indicated as an entirety at 2, embodying my invention. As shown in Figs. 11, 12 and 12a, these means consist of two members indicated at 3, 4, the latter consisting of an annulus incorporated in and interlocked to the wall I,

by a pressed on" process, whereby it is perma-- nently held against movement-rotatively and axially, relative to the wall. In carrying out this process, the wall I is formed with an opening and the metal there-around is drawn laterally to form a collar 5, having at its base and contiguous to the adjacent portions of the wall I, offsetembossments 6, disposed in spaced relation circumferentially of the collar, four such embossments being shown. Next, I form the annulus 4, preferably by a drop forging operation, the inner wall of the annulus adjacent one end being formed with recesses or notches I complementary to the embossments 6; also, the inner wall of the annulusi, at its upper end, is beveled to form an outwardly upwardly inclined surface 8. -Next, the annulus G is positioned in the collar 5 with the embossments 6 fitting into the recesses l, and by means of suitable dies, the outer marginal portion of the collar 5 is forced laterally, throughout its circumference, into engagement with the surface 9, as shown at 8 (see Fig. 7), thereby clamping the annulus 4 between the laterally bent wall 9 and wall l, the effect of which is to secure the annulus or ring in position against endwise movement and against rotative move ment by the interlocking relation of the embossments 6 and recesses 7. In this arrangement, the wall 9 forms a seat'for engagement by a portion of the member 3, as later set forth, to close, in a liquid tight manner, the container opening.

It will be obvious that the invention is not to be limited to the sequence of steps above described, since, for example, the' off-set embossments 6 may be omitted from the collar 5 during or following the formation of the latter and that the dies employed to clamp the annulus between the walls i and 9 may be shaped to strike-up the metal of the collar 5 at the base thereof, into the recesses ll. 1

By preference, before the annulus it is incorporated in the wall i, its external side wall is provided with screw threads iil, which are engaged by screw'threads on a wall of the member 3 and its top wall outwardly of the beveled surface 8, is provided circumferentially with a series of notches I l, for a purpose later to appear. The bottom walls of the notches ii are preferably inclined.

The member 3 is also by preference formed by a drop forging operation and is shaped to provide a top wall l2, and a circumferential rim or skirt l3 and an annular wall or rib it on the inner face of the wall l2, forming with the rim or skirt an annular recess or chamber H5. The inner wall of the rim or skirt I3 is provided with screw threads l3a arranged to engage the screw threads ill on the outer wall of the annulus l;

also, the annular wall or rib it is machined by a suitable tool to provide a beveled surface l ta which is arranged to engage the wall or seat 9,

when the member 3 is tightened on the member (i, to close the opening through the latter, these engaged surfaces serving to provide a liquid tight joint without the use of a gasket. The outer side wall of the rim or skirt may be of polygonal shape to take a suitable tool to facilitate tightening and extending through the walls at the closure member 3, so as to communicate with the chamber is. When the closure member 3 is tightened on the member 4 to efiect a liquid-tight engagement of the rib I4 with the seat 3 (see F18. 11), the container is closed, so that its contents cannot leak out or flow into the chamber 15 and through the opening I8, but upon loosening the member 4 and backing it up, the container contents will flow into the chamber 15 and through the opening l8, as indicated by the arrows in Fig. 12a. is indicates a vent formed in the walls of the member 4, preferably diametrically disposed to the discharge opening IS. The vent l9 communicates with the chamber l5, so that when the container is closed, as above set forth, the vent is also closed against admission of air to the container or leakage 01 itscontents therethrough. However, when the closure member is moved to its discharge position (Fig. 12a), air flows through the vent into the container.

Since the closing rib. I4 is disposed concentric to but spaced from the rim or skirt l3, the chamber l5 extends entirely around the rib l4, and accordingly the discharge opening may be enlarged circumferentially,as shown at l8a (see Figs. 17, 18, 19, 20, and 21) to increase its capacity.

Fig. 16 shows a modified form of construction wherein the metal wall I, which is deformed laterally to form the collar 50, is subjected to two draw operations to avoid undue. strains on the metal. When the collar 50 is of the shape shown, the inner wall of the annulus 4a is also correspondingly shaped.

The walls of the vent l9 are provided with screwthreads so as to receive a bolt 20, the inner end of which is arranged to project into and around the opening l8a and inwardly of the vent l9, whereby the .latter communicates with the chamber l5 independently of the spout 26. The Y spout 26 has an enlarged annular inlet end terminating in an inwardly disposedialse bead 29 which is adapted to removably and rotatively fit into the groove 28 and thus removably connects the spout 2a to the member s.- The walls or the engage the bottom wall of one of the notches H.

to thereby lock the closure member .3 to the annulus 4 (see Fig. 20). However, it will be obvious that the notches H may be omitted and the bolt 20 tightened against the annulus 4 to lock the member 3 against turning. The bolt 20 is utilized to form one element of a sealing means, to prevent tampering or unauthorized opening of the container, that is, backing-up of the closure member 3 and emptying the container of all or a portion of its contents. The other element of the sealing means consists of an integral lu'g 2| (preferably two lugs) provided on the member 3, adjacent the vent l9, so that by means of a wire 22 threaded through an opening 23 formed in the bolt 20 and openings 24 formed in the lugs 2|,

\ i and a slug 25 connecting the ends of the wire, the

closure member is sealed. The lugs 2| are provided by cutting away the metal of the member 3 at opposite sides of the vent l9, so that the remaining portion of the member 3 is utilized as the lugs 2|. By this arrangement the lugs do not project beyond the surfaces of the top I2 and skirt l3;\it also leaves a portion of the shank of the bolt 20 rexposed so that the opening 23 therethrough may be disposed below the bolt head. V

Figs. 22 to 25, inclusive, illustrate a modification wherein the closure member is arranged to removably support a spout, indicated as an entirety at 26. In this form of construction I provide the top wall l2 oi the member 3 with an annular wall 21, preferably shaped to flare outwardly whereby a groove 23 is formed between its periphery and the skirt I3. The wall 21 is disposed eccentrically to the axis of .the closure member 3 so as to extend outwardly of and spout 26 have a general converging relation toward its discharge end and preferably extend laterally to direct the flow of material from the container downwardly. At the upper portion of the spout, the spout wall is slitted at 30, the slit extending from the inlet end of the spout or head 29 longitudinally toward its discharge end. As the metal of the spout is slightly resilient,the slit 30 permits the marginal portion of the spout at its inlet end to be expanded, whereby it may he slipped over the edgeof the wall 21 in attaching or detaching the spout. The member 3 is provided with a toolsocket l1 and the outer side of .its skirt is of polygonal shape, so that while it may be operated in either direction by a tool fitting the socket or a wrench engaging the skirt, when the spout 26 is not employed, a wrench may be usedto loosen and back-up the member 3 when the spout is in position. When the spout 26 is to be used, it is applied to the member 3 before the latter is loosened and backed up; and then as this operation takes place to permit emptying of the container, the spout is held stationary, the yieldable engagement of the head 29 with the wall 21 permitting the member 3 to be rotated relative to the spout 26 when the latter is held.

. It will be noted that in my construction, no part or portion of the-filling and emptying means extend into the container and that the inner end of the collar 5 is flush with the inner surface of the adjacent container 7 wall; accordingly, full drainage of the container may be effected.

In operation, the closure member 3 is removed for filling the container. The member 3 is then screwed on the member 4 and tightened, such operation closing oif both the discharge opening and vent. To look the closure member against turning due to knocks, the bolt 20 is threaded through the vent l9 into one of the notches H,

which are placed relatively close to receive the Figs. 26 to 41, inclusive, show difierent embodiments of my invention, wherein the closure or a portion thereof fits within and has threaded engagement with a portion of the annulus, instead of extending over and enga ing its outer wall. In this arrangement, the casing of a standard type of pump may be mounted on the annulus when desired.

the lip to the closure 4'.

of the base 32 adjacent its outer end,is formed with recesses If into which the oil-sets 6 formed in the collar 5 project. Also, the upper edge the inner wall of the base 32 is beveled, as shown at 8' and the inner marginal portion of the collar is bent laterally throughout its circumference into engagement with the beveled Wall 8, as shown at 9', to thereby secure the annulus 3 t0 the wall I against endwise or axial movement, the interlocking relation between the off-sets 6 and recesses I serving to prevent rotative movement of the annulus 3' relative to the wall I. The laterally bent wall 9 forms a seat for the annular wall i4 provided on the inner side of the closure 4'. The inner side of the wall 3t is provided with screw threads l0 which are engaged by the externally threaded wall 33 of the closure 4, and when theclosure is mounted in the annulus 3' and tightened, the wall i4 engages the seat 9 in a liquid tight manner without the use of a gasket, to close the opening through the collar 5'. That side of the wall 3! adjacent the container chime or side is extended laterally to form a pouring lip 3M and diametrically opposite the lip am the wall M is formed top wall 35a of the cap 35 may be shaped to en- I close and fit over the boss.

with an opening it which serves as a vent for the container during emptying thereof, "as shown by the arrows in Fig. 31. It will be noted that the vent i5 is arranged outwardly of the seat 9' so that when the wall M of the closure 4' engages therewith, the vent I9 is closed by the latter (see Fig. The closure d is formed with recesses 36, whereby a suitable tool or other device may be employed to tighten and loosen it; but it will. be obvious that the closure 4 may be formed with a recess as shown in Fig. 15 or a boss as shown in Figs. 13 and 14;, or a polygonal flange as shown in Figs. 37, 38 and 40.

The form of construction shown in Figs. 26 and 27 lends itself for sealing against tampering or unauthorized opening by means of a sealing cap formed of thin sheet metal, asindicated as an entirety at 35, which is capable of deformation or mutilation in the event any attemptis made to remove the cap. In this form of sealing means, the upper end of the annulus d throughout that portion of the side wall 3i which is concentric to the axis of the annulus, is provided with an integral, up-standing rib 36, the outer wall of which is formed with a groove 36a. The cap 35 is shaped to provide a top wall 35a of circular shape and substantially equal in diameter to the outer side of the rib 36 and an extension'dtib, which is off-set in a. plane below the top Wall 35a, as shown at Six, to lie over and engage the pouring lip 3la, to close the latter to prevent access through The marginal portion of the top wall 35a is curled over and inwardly, as shown at 35a, the 'free' edge of which portion is arranged to extend into the groove 36a; whereas the extension 351) is provided with a flange 35b arranged to engage the outer sides of the lip 311a so that the cap 35 cannot be rotated about the annulus d. and thus expose the closure through the lip am; As the cap 35 is formed of resilient metal, its curled over marginal portion 35a may be readily sprung over the rib 36 to efiect the projection of its free edge in the groove 3611. As the cap is readily deformable, any attempt'to remove it will result in detection. It will be obvious that the rib 36 may be shaped to form a shoulder :and

Referring to Figs. 35 to 41, inclusive, 3:: indicates an annulus and 4:: indicates a closure. The annulus 3a: is substantially similar in construction to the annulus 3' and mounted in the same manner-in the wall Ix, except that the side wall 3L1: is concentric to the axis of the annulus throughout its circumference and not extended at one side to form a pouring lip. The wall 311: is formed with a vent like. The closure 4:: is also mounted in the annulus 3x, similarly to the closure 3 to close the opening through the collar 5a: and vent lSx, but difiers from the closure 3' in that it is formed with an outlet preferably consisting of a recess 34:: formed in its outer face and a passage 3'! extending from one side of the threaded portion 33x, above the closing wall Mac, to the recess 342. If desired, the recess 34.1: may be shaped to take a tool as shown in Fig. 15 and serve as a means for tightening and loosening the .5932. The side walls 31a of the outlet opening 31 preferably extend radially, as shown'in Figs. 37 and 40.

Since the discharge of the material takes place through the closure, that'is, through the opening 31 and recess 3%, it may be provided on its outer surface with an annular wall, as shown at El in Figs. 22, 23 and 25, to removably support a spout. Also, the side wall 3h: may be provided with a rib, as shown at 38 in Figs. 26, 27,. .30, 31 and 34, whereby the container may be sealed by a suitable deformable cap.

In the form of closure dz shown it is provided with a polygonal flange 38 whereby a suitable tool may be utilized to tighten and loosen it. In this arrangement the flange 38 is formed with a threaded opening 39 to receive a bolt or set screw dd, which, when tightened against the wall 3&1 (see Figs. 39 and 40) serves to lock the closure 3:: to the annulus 3a.. The head of the bolt dd is formed with an opening 600. (the head may be formed with two through openings disposed at right angles to each other) alined with openings 4H formed in lugs 42 integralwith the flange as and disposed upon opposite sides of the opening 3Q, so that a wire 43 may be threaded through the openings 48a, ti and its ends connected by a suitable lead slug M, whereby the closure is sealed.

From the foregoing description it will be noted that in the manufacture of containers, less equipment is required, less labor employed and fewer parts needed to be stocked and handled, all of which tends to more economical production, and since fewer parts are required for each container, there is a substantial saving in cost of fittings therefor. a

It will also be noted that the container may be closed without the use of gaskets between the annulus 4 and wall I and collar 5, or between any portion of the container and the closure member since the latter engages directly with the collar 5, that is, the laterally bent portion It will also be noted that the sealing means, in

with the locking means between the closure and the annulus, o that the locking means cannot be removed or loosened nor the closure loosened without breaking the seal. In place of a locking bolt, a screw having a kerf in its outer end may be employed to avoid a projection extending beyond the surfaces of the closure.

To those skilled in the art to which my invention relates, many changes in construction and widely differing embodiments and applications of the invention will be apparent without departing from its spirit and scope; My disclosures and the description herein are purely illustrative and not intended to be in any sense limiting.
